The Painted
Desert is part of Petrified Forest Nat'l Park, on the northern end
of it.
PETRIFIED
FOREST NATIONAL PARK -- SOUTHERN END
The
Visitor Center has an excellent, 20-minute movie explaining
the petrified wood phenomenon and the park in general. Make
sure you catch it if you're around.
If
you're the hurried type, count at least 3 hours to visit the park.
If you're the contemplative kind, the whole day won't be enough...
